To It "Iv/mm ifnm-y (en/merit:

Be it. known that l, PA'rmcK J. MOONEY, a

citizen of the United States, residing at Bra zil, in the county of Clay and State of Indiana, have invented 'sult et l'ee t certain new and useful Improvements in l oraminous Fire Plates or Covers, of which the following is a specification.

it is universally recognized that a high per cent. of thethei'mal ellieienc'v of coke, coal,

wood, and all the other substances used as fuel for heating and cooking or otherpurposes is lost or wasted as a result of the incomplete combustion of carbon with oxygen, the carbomicerms oxid result ng from this incomplete combustion being ordinarily in the present practice of burning fuel] wasted through the outlet pi 'ie. in view of the fact that the carbon monoxid formed by the incomplete combustion of carbon with oxygen is ,ii'iilannnablc it is evident that the thermal efficiency of a. bed of coals or other fuel may' be greatly promott-id if the carbon monoxid were to be completely con sumed or burned in the stove orother magazine for the fuel and not rior atmosphere, as is One of the object. provide. an improved complete combustion material of whichcoal largely composed and the invention is to provide a simple device which may be readily applied to any bed of fuel and which in-its action will distribute the draft uniformly and will increase the draft and accelerate the process of combustion whenever desired and which will effect, as oxygenizing of of my invention is to means for eflecting a of the carbonaceous before stated, the complete the on1hustible gases, which will confine such gases until they are thoroughly coinmingled with the oxygen and consumed, while at the same time will not detract from the draft, but, on the other hand, will materially assist the same, and which Will as a reimproved economies in the consumption of fuel for heating and other purposes.

With this and other purposes in view, as will hereinafter appear as the description. proceeds, my invention consists, essentially, of a foraminous plate designed to be held directly upon or in superposed relation to the bed-of live coals or other fuel without any material support other than said bed of fuel and preferably spaced, slightly fri'inn the inor carbon HIODOXld 'asted to the eXte-- now commoiily the case.

and other fuel is so} the further object of terior walls of the stove orot-her magazine containing the bed of fuel. 7

For a full descruition of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the companying drawings, in which--- Figure 1 is a side elevation of a heatingstove with parts broken away to show my improved article of manufacture located therein in juxtaposition to the bed of fuel. Fig. 2 is a detail perspective view of one form in which my invention may be embodied. Fig. 3 is a similar view of another form Corresponding and like parts are referred to in the following description and indicated in all the views of the drawingsby the same reference characters.

Referring to the drawings, the numeral 1 designates a stove, which may be of any dc-v sired form and construction and which is here portrayed for the purpose of illustration only. I t is provided with a lower damper .2, grate 3, and fuel-inlet door 4, all of which may be of any preferred construction or design. 5 designates the bed of 'fuel. Upon the bed of fuel rests my improved plate 6,

which is foraminous, as shown, being in the present instance provided with apertures or orifices '7, which may be of any preferred number, shape, or locationwith respect to the margin of the plate. The plate 6 is superposed on the bed of fuel and rests directly thereon without other support in the magazine of the stove, an d its margin or outer edge is preferably spaced somewhat from the in nor wall of the magazine, as shown. In that form of my invention illustrated .in Fig. lthe plate 6 is provided with a superadjacent and contiguous plate 6, which is also foraminous and is pivotally mounted with respect to the plate 6, so that as said plates are turned axially with respect to each other the openings 7 and the openings '7 in the plate 6 may be regulated. with relation to their areas so as to provide more or less openings as may be desired and so as to provide also openiogsofdifferent sectional areas.

When the bed of coals or other fuel is burning, it is manifest that by placing my iu'iproved article of manulaeture-namely. the foraminous plate. ---direct-ly upon the bed of fuel and supported thereby the oxygen on tcring the magazine below the grate-bars through the damper 2 or in any other manfollowing description and etc-- vides a plurality of drafts, which will act in.

the nature of suction-orifices to insure the proper combustion, and the carbon monoxid will burn as it issues out of said orifices,which thereby constitute flame-jets. As the fuel is thus burned and the process of disintegration and combustion accelerated by my im proved device the latter, as it is supported solely by the fuel-bed, will sink down with said bed, and thereby always maintain its properposition with relation thereto; be noted that my improved plate controls the process df-- combustion and promotes the thermal efficiency of the fuel-h ed to a marked degree. It is to be understood that the plate may be composed of any substance or material that is not injurio'usly affected by the heating and that it may be composed of material which will incandesce or otherwise, as desired. 1 Moreover, the plate precludes harmful contact of the bed of fuel with air, as even if the door 4 of the stove is open above the live fuel the plate will form a covering or blanket for the fire, and it will thus be maintained burning in a subdued manner, and the combustible gases will be. consumed and unnecessary exhaustion of the fuel b superfluous air coming in at the door wilf be prevented.

As shown in Fig. 2, the plate there desig- It will nated 8 may be of one inte ral structure instead of two plates pivotally connected together, as shown in Fig- 1, or, as illustrated in Fig. 3, the plate there designated 9 may be constructed in two' sections detachably and 'ivotally connected together by means of u s may be detached from each other for convenient insertion into the stove, and thus readily connected in operative position. It is to be understood that the plate or cover may be either rigid or flexible, as desired.

Having thus described the invention, what is claimed as new is- 1. As a new article of manufacture a foraniinous plate designed to be superposed on a bed of fuel, for the purpose specified.

2. As a new article of manufacture, a foraminous plate designed to be superposed on a bed of live fuel and to be supported solely thereby said plate being provided with means for regulating the area of its openings.

3. The combination with a stove or. the

like, of a foraminous plate designed for inser tion in said stove, and for superposition upon the fuel therein, said plate being supported directly upon and solely by said fuel whereby it will sink as the bed lowers, and said plate being spaced from the walls of the stove.

4. The combination with a stove or the like of a cover for the fuel-bed, said cover be ing supported directly upon and by said bed, and being foraminous, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
